NEW YORK, April 15 (Reuters) - U.S. stocks ended a volatile
session higher on Tuesday, lifted by gains in such blue-chip
names as Coca-Cola and Johnson & Johnson, though persistent
weakness in momentum names limited the Nasdaq's advance.

Coke and J&J, both Dow components, climbed after their
results while recent outperformers fell, a sign that investors
were rotating from growth stocks into value ones. In recent
weeks, high-growth stocks have been under pressure after a
meteoric rise in their prices took valuations to levels that
appeared unsustainable.

The three major U.S. stock indexes fell for much of the
session before rebounding in afternoon trading. The Nasdaq moved
in a 108.77-point range, and at its lows of the day, it was
within 0.3 percent of 3,934.53, the level that represents a 10
percent drop from its recent intraday peak, hit on March 6.

"The market is trying to stabilize, and investors are
looking for high-quality names that have stability in their
earnings and prices," said Bruce McCain, chief investment
strategist at Key Private Bank in Cleveland, Ohio. "This
afternoon's move is part of that same flight to quality."
